Subject: Characterize Letting Submodules Inherit Big Wire Loading Models
John :
Do you know why the characterize function places the top module's wire
load module on the cell you're characterizing?? This seems wrong to me.
It means that if I have a 40K gate die size on the top level, and I
characterize a 100 gate sub-module, that sub-module ends up with delays
for the 40K gate die! I have been undoing this "feature" after every
characterize (big pain in the butt). Any suggestions?
